Help keep FreeBSD tidy
A small Ruby script for helping deal with cruft on pkgng-based systems like FreeBSD.
Perhaps most interesting is the implementation of
checkrestart, a feature similar to the Debian-goodies
program of the same name, which can find running processes
which may need restarting following an upgrade.
# pkg-cruft checkrestart [MISSING EXECUTABLE] (tmux-2.7)? running as 17319 (tmux) [MISSING EXECUTABLE] (zsh-5.5.1)? running as 20115 (zsh) [MISSING EXECUTABLE] (weechat-2.2)? running as 36747 (weechat) /usr/local/bin/mosh-server (mosh-1.3.2_4) running as 53815 (mosh-server)
This is done by parsing
procstat -va, locating executable
mappings backed by files without a known path, and then
mapping those back to executables and their respective
Accuracy is somewhat limited by the FreeBSD kernel retaining less information about defunct files, but I find it works quite well.
pkg-cruft also supports locating unpackaged files, directories which contain
no packaged files, finding binaries using obsolete or missing libraries,
and listing packages that are no longer provided upstream.
